Methods for treating anatomic tissue defects such as patent foramen ovale (PFO) generally involve positioning a distal end of an elongate catheter device at the site of the anatomic defect, exposing an expandable housing and energy transmission member out of the distal end of the catheter device, engaging the housing with tissues at the site of the anatomic defect, applying suction to the tissues via the housing to bring the tissues together; and applying energy to the tissues with the energy transmission member to substantially close the anatomic defect acutely. Apparatus generally include an elongate catheter body, a housing extending from a distal end of the catheter body for engaging tissues at the site of the anatomic defect, and an energy transmission member adjacent a distal end of the housing, the energy transmission member having at least one substantially planar surface.
